Ultrex Plus
Double Braid
Ultrex Plus is a double braid constructed of an inner load baring core of High Modulus Polyethylene (HMPE), treated with Maxijacket coating for enhanced toughness. Sleeved with high-tenacity polyester, Ultrex Plus is spliceable, using conventional high-modulus splice techniques or the new Yale tuck splice, which shortens the bury portion and minimizes the length of the larger diameter associated with a bury-type splice.

Dielectric Strength
The maximum allowable leakage for clean, dry Ultrex Plus is 100 micro-amperes when tested at 100kV per Yale Method 712-1701 Rev 1 “Routine Production Test.” Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
